Abstract
A control device including first and second operators connected in parallel to a signal to be controlled through respective potentiometers or voltage dividers which adjust the respective threshold values of the system. One operator transmits a first response when the input signal exceeds a value corresponding to an upper threshold and another response when the input signal falls below that threshold. The second operator provides corresponding responses relative to a lower threshold of the input signal. The responses of the first and second operators are fed to a third operator whose control is at all times a function of the outputs of the first and second operators, the output of the third operator being used for control.
